The oxygen minimum zone (OMZ) of the Eastern Tropical South Pacific (ETSP) is 1 of the 3
major regions in the world where oceanic nitrogen is lost in the pelagic realm. The recent …

Active expression of putative ammonia monooxygenase gene subunit A (amoA) of marine
group I Crenarchaeota has been detected in the Black Sea water column. It reached its …

We investigated the pathways of N 2 production in the oxygen‐deficient water column of the
eastern tropical South Pacific off Iquique, Chile, at 20S, through short anoxic incubations …

Nutrient measurements indicate that 30–50% of the total nitrogen (N) loss in the ocean
occurs in oxygen minimum zones (OMZs). This pelagic N-removal takes place within only ∼0.1% …

Nitrite oxidation is the second step of nitrification. It is the primary source of oceanic nitrate,
the predominant form of bioavailable nitrogen in the ocean. Despite its obvious importance, …

A combination of stable isotopes ( 15 N) and molecular ecological approaches was used to
investigate the vertical distribution and mechanisms of biological N 2 production along a …

We performed incubation experiments with 15 N‐labeled nitrogen compounds to investigate
the vertical distribution of pathways of N 2 production through the suboxic zone of the …

Permeable or sandy sediments cover the majority of the seafloor on continental shelves
worldwide, but little is known about their role in the coastal nitrogen cycle. We investigated the …

The effects of three metabolic inhibitors (acetylene, methanol, and allylthiourea [ATU]) on the
pathways of N 2 production were investigated by using short anoxic incubations of marine …

In a study of consumer perceptions, we examined three areas related to the pricing of green
products; the premium consumers are willing to pay for a green product, the relationship …
